t夸克圈对TC理论的中性PG玻色子反常耦合的影响

Top-loop Correction to TC Neutral PG Boson Anomaly Coupling

推出了ＴＣ理论的中性ＰＧ玻色子与规范玻色子（Ｚ、γ、ｇ）的总耦合拉氏量，计算了ｔ夸克圈对中性ＰＧ玻色子衰变宽度的影响．结果表明ｔ夸克圈能有效地增加反常耦合强度，为在实验上寻找ＰＧ玻包子提供了理论依据．

The total effective lagrangian of the gauge boson couplings to the neutral PG(Psudo-Goldstone)boson in technicolor models is developed.The effect of t-quark loop on the anomaly coupling is computed.Such effect significantly changes the coupling strength.The result is in favor of the detection of the neutral PG bosons.
